摘　　要：目的研究后勤物资储运箱式装备,验证其组合材料构成整体后在极温负载约束下的稳定性与可靠性,降低生产制造成本。方法按照GJB 4361—2002中1C方舱要求,以Q235B型材设计箱体架构,Q355E整幅面波纹型围护形成整箱结构,通过计算推演,采用ANSYS仿真模拟,基于GJB 5727—2006进行整箱极温环境负载贮存试验,综合研究大尺寸箱式装备在特殊条件约束下的实际工作性能。结果该箱在常温和–20、–45℃等3类约束下模拟仿真的变形量符合使用要求,该箱在–45℃、局部5 t负载时,工作稳定,且无结构性失效。结论仿真模拟和试验相互佐证,在Q235系列材料突破理论冷脆转变温度产生塑性变形时,箱体动态分散应力、整体材料组合运用与闭环结构形成的协同效应可形成形位补偿,局部互为增强效果。最终研制出成本可控,且适应–45℃环境下重载贮存的后勤物资储运箱式装备,为未来模块化箱式装备成本控制、工艺设计、整箱试验及工业化研究提供了强有力支撑。The work aims to investigate the logistics material storage and transportation containerized equipment,validate the stability and reliability of the combination of materials that constitute the overall structure under extreme temperature and load constraints,and reduce production and manufacturing costs.The container was designed according to GJB 4361-2002 for 1C cabins,with Q235B profile for the container framework and Q355E corrugated cladding for the entire container structure.Through computational deduction and ANSYS simulations,and based on GJB 5727-2006,an extreme temperature environmental load storage test was conducted on the complete container.Throughcomprehensive study,the actual working performance of large-size containerized equipment under special conditions was examined.The results of deformation amountscomplied with the operating requirement under three constraints:normal temperature,–20℃,and–45℃.Experimental observations showed that the container worked stably and without structural failure under an environmental temperature of–45℃and a local load of 5 tons.It is concluded that simulations and experiments support each other,demonstrating that dynamic stress dispersion occurs when Q235 series materials exceed their theoretical ductile-to-brittle transition temperature.The overall material combination and the closed-loop structure effectively compensates for deformations and locally enhances each other.Ultimately,a cost-effective logistics material storage and transportation containerized equipment that can adapt to heavy loads in a–45℃environment is developed,providing strong support for future modular containerized equipment cost control,process design,whole container testing,and industrial research.
